[type_traits][regex] VC++ __fastcall /clr
by Edward Diener 28 Apr '06

28 Apr '06

Since no one responded to this in the boost user group, I will post it here in this group. When compiling managed code in VC++ .NET, which is any of the /clr compiler options, the programmer can mix both CLR classes and regular C++ classes. In the regular C++ classes, Boost should work fine. The VC++ macro which tells one that managed code of any kind is being compiled is _MANAGED, which is defined if managed code is being compiled else it is not defined. So when any of the /clr compiler options are being used _MANAGED is defined, else it is not defined. The VC++ compiler issues compiler warning C4561 whenever managed code is being compiled and __fastcall shows up as a calling convention in any way. Obviously the programmer can turn off this warning via a VC++ #pragma, but I am wondering if Boost could not change some of its headers to avoid this warning. In Boost bind and mem_fn, the programmer has to specifically ask for __fastcall support via special Boost macros to have any functions declared with the __fastcall calling convention, so nothing should be done there since it is clearly a programming error if he does so while compiling managed code. However there are two other places in Boost which I have discovered where functions with the __fastcall calling convention are declared without the programmer doing anything. The first, and most cumbersome reagrding warning messages, is in type_traits in the helper header files type_traits\detail\is_mem_fun_pointer_tester.hpp and type_traits\detail\is_function_pointer_tester.hpp. Since many other libraries, lambda in my case recently, uses type_traits, might not these headers be changed so that when VC++ is the compiler and _MANAGED is defined, the __fastcall versions of these helper functions are not declared ? The second, which I have not encountered but which I saw while searching through Boost header code, is in regex\config.h and I do not know, given some other macros there, whether BOOST_REGEX_CALL can ever be __fastcall when compiling with /clr, but if it can perhaps a change can be made there also. I know that it is not the purpose of Boost to try to accomodate C++ .NET programmers creating /clr compilations using Boost, especially when just warnings and not errors are issued. But in this case, using the predefined macro _MANAGED in VC++ and BOOST_MSVC, it would seem this acoomodation could be made. So I would like the Boost developers of type_traits, especially since it is used by so many other Boost libraries, and regex to consider it.

Class views on an associative container
by SeskaPeel 28 Apr '06

28 Apr '06

Hi list, I'm looking for a "multi-class container", with access to sub-containers of elements depending on their class. All elements are derived from the same base class, and I want to have "views" of containers of final classes, or even intermediate classes. This container would be associative, like a map. As instance if I have // Base class class A {} ; // Intermediate classes class B : public A {} ; // Final classes class C : public B {} ; class D : public B {} ; class E : public A {} ; I want a container that can hold any A-derived class, on which I could have views of sub containers of class C, D or E, and even a sub container of intermediate class B. I looked at multi-index, but no such feature seems to be feasible. And I have no need of multiple indices, as I access all theses elements by their ID which is a member of A. Any hint on how I could implement this? Cheers, SeskaPeel.

At my implementation basic_registry_proxy has only simple get/set functionality: virtual bool get(const path, string&) const = 0; Template function belongs to wrapper which contains pointer to basic_registry_proxy. I was trying to simplify my class hierarchy and produce silly indeed interface. I am sorry. Regards, Alexander

Testing Property Tree xml parser
by Jose 28 Apr '06

28 Apr '06

Hi, I am trying to finish my review of the Property Tree. I find the scope of the library for program configuration very useful. I am currently testing only the read_xml parsing, and although it is only meant for very simple xml files i find its xml support very very sketchy. I've performed multiple experiments with rss feed files, which are very simple xml files. This is the loop I am using to test different xml paths using a command line utility: BOOST_FOREACH(ptree::value_type &v, pt.get_child( argv[2] )) cout << "value: " << v.second.data() << endl; Below is a list of my experiments: 1. parsing the artima.com spotlight feed Result: FAILED The path is rdf:RDF.item.title and I get invalid character entitly. I think the parser should support the semicolon within the tag name, given that in many cases the config files might be generated by real xml programs which use namespaces and it should be able to read them even if it does not support save. 2. parsing the MSDN visual c++ feed Result: FAILED The path is rss.channel.item.title and I get an "xml parse error". Is there a posibility of getting more meaningful errors ? 3. parsing the main CNN feed Result: FAILED The path is rss.channel.item.title. This query fails with no error but if the path is shortened to rss.channel.item it dumps all the values within item, but there is no value at that level (only nested tags) 4. Parsing the Google News RSS feed Result: FAILED The path is rss.channel.item.title. I get "Invalid character entity error". A more meaningful error should be possible with the position in the file where the entity occurs. 5. Parsing the Google News Atom feed Result: FAILED The path is feed.entry.title. I get "Invalid character entity error". regards jose

[SoC] Boost not listed?
by Joaquín Mª López Muñoz 28 Apr '06

28 Apr '06

As of now, the following page http://code.google.com/soc/ does not list Boost amongst the mentor organizations. Maybe we missed some deadline or were rejected, is it transitory? Maybe a ping to soc2006support(a)google.com is in order? Thank you, Joaquín M López Muñoz Telefónica, Investigación y Desarrollo

[Property tree review] Comments & layout information
by Marcin Kalicinski 28 Apr '06

28 Apr '06

I have an interesting idea how to preserve comments & layout information. The relevant structures should be included in the tree under a special meta key: Config file: key1 data1 ;comment before key2 key2 data2 ;comment after key2, on the same line The resulting tree might look like that: key1 data1 key2 data2 _metadata_ { key1 { row 1 column 1 } comment "comment before key2" { row 2 column 1 } key2 { row 3 column 1 } comment "comment after key2, on the same line" { row 3 column 15 } } This way it is easily accessible using ptree interface, it is readable, editable, and it is possible to manipulate it programatically. And above all, it does not require any extra support from ptree, only from the parsers. With some effort it also allows 100% reproduction of original layout. --Marcin

property tree & registry approach
by Alexander Belyakov 28 Apr '06

28 Apr '06

May be it will be interesting to compare another approach to the proposed Property Tree Library. I was highly pleased to see this library but here I focused at differences which could offer more flexible and scalable solution at some aspects of registry behavior. Of course, this flexibility has some cost and functionality of libraries not overlapped fully. But the registry functionality is the most interesting part for me. class path; class basic_registry_proxy { public: ... template<class T> virtual bool get(const path, T&) const = 0; template<class T> virtual bool set(const path, T&) = 0; ... } //basic_registry_proxy - represents the whole regestry tree. //Not any key but whole tree. //path - identify actual key at basic_registry_proxy. class simple_registry : public basic_registry_proxy; // uses win API class win_registry : public basic_registry_proxy; // uses win API class thread_safe_registry : public basic_registry_proxy; // uses Boost.Thread class dispersed_registry : public basic_registry_proxy; // stores data at multiple files class basic_parser { public: virtual load(basic_registry_proxy*, const char* PathatAtProxy = 0) const = 0; virtual save(basic_registry_proxy*, const char* PathatAtProxy = 0) const = 0; } class win_registry_parser : public basic_parser; class XML_registry_parser : public basic_parser; usage example: // copy windows registry to simple_registry (1) win_registry_parser wregparser("HKEY_LOCAL_MACHINE/SOFTWARE/"); simple_registry sregistry; wregparser.load(&sregistry); // convert windows registry to simple_registry (2) win_registry wregistry; simple_registry sregistry; copy(&wregistry, path("/"), &sregistry, path(/)); Assume that at windows registry we have such structure: somekey1 defaulttext1 REG_SZ somekey2 somekey3 defaulttext2 REG_SZ somevalue1 somedata REG_SZ somevalue2 1234 REG_DWORD Lets choose prefix "#" for subsidiary attribute information. So we could get new representation of registry. somekey1 defaulttext1 { #role key {} #type REG_SZ {} somekey2 { somekey3 defaulttext2 { #role key{} #type REG_SZ {} } somevalue1 somedata { #role value {} #type REG_SZ {} } somevalue2 1234 { #role value{} #type REG_DWORD {} } } } At this case the new registry syntaxes is richer than windows registry one.
